Assignment 2 Structural Modeling and Behavior Modeling
Structural Modeling and Behavior Modeling
Refer to the functional model attached to complete this question.
Based on your performance, ABS management was so satisfied that it wants you to develop both the structural and behavior models. This way, ABS can fully understand both the interaction that would take place between the users and the system, and the system itself in greater detail.
Note: You may create and / or assume all necessary assumptions needed for the completion of this question.
Write a four to five (4-5) page paper in which you:
- Create Class-Responsibility-Collaboration (CRC) cards and a class diagram based on the functional models through the use of graphical tools in Microsoft Word or Visio. Note: The graphically depicted solution is not included in the required page length.
- Identify each use case in the functional model and create a sequence and communication diagram for each scenario of each use case identified through the use of graphical tools in Microsoft Word or Visio. Note: The graphically depicted solution is not included in the required page length.
- Create a behavioral state machine for each of the complex classes in the class diagram.
- Perform a CRUDE analysis to show the interactivity of the objects in the system.
- Perform a verification and validation walk-through of each:
- Functional model
- Structural model
- Behavioral model
- Revise the requirements document created in the attachment with additional information found in this assignment and document the assumptions.
- Use at least three (3) quality resources in this assignment. Note: Wikipedia and similar Websites do not qualify as quality resources.
Your assignment must follow these formatting requirements:
- Be typed, double spaced, using Times New Roman font (size 12), with one-inch margins on all sides; citations and references must follow APA format
- Include a cover page containing the title of the assignment, the student’s name, the professor’s name, the course title, and the date. The cover page and the reference page are not included in the required assignment page length.
- Include charts or diagrams created in Visio and the completed diagrams / charts must be imported into the Word document.

THE FOLLOWING IS THE IT PROCUREMENT FRAMEWORK: PROCESSES, SUB-PROCESSES, AND KEY ISSUES
The IT Procurement Process Framework provides a way to describe systematically the processes and sub-processes involved in IT procurement. The illustration below shows in summary how the process takes place in IT procurement. Each of these major processes consists of a number of sub-processes. M1, M2, M3 represents the processes at the management level. D1, D2 and D3 represent the deployment process.
http://www.ittoday.info/Articles/Managing_IT_Procurement_Process.htm
Deployment Processes
Deployment processes consist of activities that are performed EVERY time an IT product or service is acquired. Each procurement process can be determined in terms of a life cycle that starts with requirements determination, proceeds with activities involved in the real acquisition of a product or service, and is finished as the terms specified in the contract are done. Each IT product or service that is procured has its own individual consideration of this deployment life cycle.
D1-Requirements determination is the process of determining the justification of business, requirements, specifications and features required and approvals to proceed with the procurement process of IT service and products. It includes sub-processes like organizing project teams, using cost-effective or any other analytic techniques to justify investments projects, determining alternatives, assessing related risks and benefits defining features, and obtaining required approvals to proceed with the IT products procurement process.
D2- Acquisition is the process of evaluating and selecting required suppliers and completing procurement arrangements for the necessary goods and services. It involves identification of sourcing alternative finance, generating feedbacks to suppliers, reviewing supplier proposals, and negotiating contracts with supplying companies and firms.
D3- Contract fulfillment5 is the process of managing and co-ordinating all activities required in fulfilling contract specifications. It involves evaluation of orders, accepting the products or services, installation of systems required, management of post-installation processes such as warranty and maintenance services and procedures.
Management Processes
Management processes refers to all activities involved in the governance of IT procurement processes. The general level of IT procurement management processes are supplier management, asset management, and quality management.
M1 –Supplier management is the process of using customer-supplier relationships to enhance the value to the business. It involves activities like development of a supplier portfolio strategy4, development of relationship strategies for key suppliers, assessing and evaluating supplier performance, and ensuring effective communication with suppliers.
M2- Asset management is the process of maximizing the utilization of all IT assets throughout their entire life cycle to meet the needs of the business objectives. It involves activities like development of IT assets management strategies and implementation policies, development and maintenance of the asset, evaluation of the life cycle expenses of IT asset ownership, and management of asset disposal policies.
M3- Quality management refers to the process of assuring consistent development of the IT procurement process for IT purposes in an organization. It involves activities such as product testing, statistical process control measures, accepting testing, and facility audits from the IT firms.
